CARTON.

Application filed December a, 1923. Serial No. 678,122.

This invention relates to cartons more particularly those adapted tocontain articles of irregular shape.

While not restricted to such use the invention is especially applicableto cartons for packing fiat triangular drinking cups. The packing ofsuch cups involves two problems, first, the provision of a carton whosesides will conform to the general triangular contour of such cups, and,second, the provision of means for allowing for the fact that such cupsare thicker at the small end than they are at the large end andconsequently will not stack evenly.

One of The objects of the present invention is to provide a cartonadapted to pack articles of non-rectangular contour.

Another object of the invention is to provide a carton adapted to packsecurely articles of uneven thickness.

Other and further important objects of this invention will be apparentfrom the disclosures inlthe drawings and specification. The invention'(in a preferred form) s illustrated'in the drawings and hereinaftermore fully described.

I On the drawings:

Figure 1 is a perspective viewof a car ton constructed in accordancewith the pres-' ent invention.

Figure 2 is a section on the line 22 of Figure 1 with the top of thecarton open.

Figure 3 is a perspective view of the upper part of the carton partlyopened.

Figure 4 is a plan view of the carton collapsed flat for shipment orstorage.

Fi ure 5 is a plan view of the blank from whic the carton is made.

As shown on the drawings:

The carton is formed from a blank 10 composed of three broad strips 11and three narrow strips 12 alternately arranged with lines of foldtherebetween adapted to form the six vertical sides of the carton. Whilethe carton is actually hexagonal since every other side is much narrowerthan the intervening sides the cross-section is of general triangularform. The hexagonal or flattened corner form has several advan tagesover a truly triangular shape. In the the cartons will nest in a smallerspace than they would otherwise.

The body of the carton also includes a pasting strip 13 for attachmentto opposite edges of the blank.

Two of the strips or side portions 11 are provided at each end withextensions 14 and 15. Each of these extensions includes a.

main portion of similar configuration to the cross-section of the cartonand, therefore, adapted to close the bottom and top of the latter. Tothe main portion of the extensions flaps 16 and 17 are connected withintervening lines of fold.

These flaps are adapted to be tucked inside the wall of the cartonbetween the latter and the contents thereof to aid in holding the mainportions of the extensions in position.

If desired glue or other adhesive may be employed for cementing togetherthe flaps 14 and 15, particularly at the bottom of the carton.

It will be observed that the extensions 14 and 15 and their attachedflaps 16 and 17 are not identical in form. The extensions 15 andattached flaps 16 are out 01f in line with the line of fold 18 so that,after the pasting strip 13 has been secured to the opposite ed e of theblank to form an openended tu the latter may be collapsed about the lineof fold 18 to give a fiat article having two straight edges as \,shownin Figure 4.

While one of the lines of fold required in making the carton, such as18, may be utilized in collapsing the carton, it is also necessary toprovide an additional line of told 19 as shown in Figure 5.

As shown in Figure 2 the carton is designed to hold a stack of flatpaper cups 20 arranged with their thickened bottoms to the right-handside of this figure. To provide uniform pressure upon the cups at bothtop and bottom in spite of the inequality in thickness, fillers-arearranged in the carton preferably, as shown, both at top and bottom.These fillers may conveniently be formed of a single piece of bentpasteboard, the body part 21 being of similar configuration to thecross-section of the carton and extending thereaeross While the flangeportion 22 is arranged to engage the top or bottom member of the cartonand thereby hold the body portion at an angle to such end of the carton.

My improved carton preferably is formed of commercial pasteboard, butmay be made of any comparatively thick paper capable of being bentangularly, as by scoring, and in using the term thickened paper in theclaims, I wish to define a paper stiff enough to maintain its shape, butwhich if bent to too acute an angle is liable to iupture along the lineof bend. i

I am aware that many changes may be made, and numerous details ofconstruction may be varied through a wide range without departing fromthe principles of this invention, and I therefore do not purposelimiting the patent granted hereon, otherwise than necessitated by theprior art.

I claim as my invention 1. A carton of thickened paper, bent angularlyto the desired cross sectional configuration, two lines of bend beingformed at each angle. thereby providing obtuse angles at these points.

2. A carton of thickened paper, bent angularly to substantiallytriangular cross sectional configuration, the apices of the trianglebeing formed with a double bend, thereby forming angles double theobtuseness of the normal angle.

3. A carton, and a filler for one end of the same composed of a bentsheet of material having one portion extending along and in contact withone side of the interior of the carton and another portion extendingobliquely across the entire carton.

4. A carton, and a filler for one end of the same composed of a sheet ofpasteboard having a body portion of substantially the same configurationas the interior of the car ton and a flange portion along one sideadapted to engage the end of the carton and thereby hold the bodyportion at an angle to such end of the carton.

5. A blank for making cartons comprising a sheet of material includingthree narrow and three wide strips alternately arranged with lines offold therebetween, and extensions on the ends of certain of the Widestrips, said extensions each including a portion of similarconfiguration to the cross section of the carton and a flap adapted toextend inwardly between the side of the carton and its contents.

6. YA carton comprising a tube of hexagonal cross-section, every otherside being of smaller width than the intervening sides. and extensionsat each end from t o of the wide sides, said extensions including aportion of a configuration similar to the crosssection of the carton anda flap adapted to extend inwardly between the side of the car-- ton andits contents.

7. A carton comprising a tube having a cross-section of generaltriangular form, and extensions at each end from two of the sides, thethird side having a line of fold therein to allow the carton to becollapsed, said extensions including a portion of similar configurationto the cross-section of the carton and a flap adapted to extend inward-1y between the side of the carton and its contents.

In testimony whereof I have hereunto sub scribed my name.

CESARE BARBIERI.
